You keep going along with her plans

You decide that you don't want to risk making her more upset so it would be best to just put your pride aside and wear the panties for now, your sure you'll be able to smooth things over soon and then you and Jane can laugh all this off as one big joke. You take a look at the panties, they're not too **** just a simple yellow brief pantie with white hearts covering them and a yellow lace bow on the front. You consider yourself lucky that it at least wasn't a thong or some skimpy piece of lace and start to slide them up your legs. After putting them on it becomes really obvious that there isn't much room at the front, luckily your not the biggest in that department so with a little shifting you can get everything in place and somewhat comfortable although this is the first time you've been grateful about you small dick. One thing you quickly try to put out of your mind is how soft they feel compared to your usual underwear, you can feel your self getting a little hard from the panties rubbing against you before you distract your self by continuing to get ready.

After getting dressed you head down stairs to wait for Jane but she's already there waiting for you instead "show me the panties, I want to make sure your wearing them" she demands. Your glad you decided to wear them after all and not try to trick her as you pull your pants down to show the panties. She snaps a picture before you can even ask why she has her phone in her hand and says "Good now I have proof to show mom if you try to step out of line, let's go, we have a long day of shopping ahead of us" she says while heading for the door, you think to your self that it shouldn't take that long to make you buy panties but remember that she was already going shopping to begin with so your probably going to be dragged around with her all day. What's really on your mind is how she can now use the picture to make your mom think you actually were sneaking her panties out of the laundry if you don't keep her happy.

You arrive at the mall, for a moment you worry if someone will notice your wearing panties but then you remember your sister is about to make you buy your own so there's really no point. Right as you enter your sister says "right so since its the quickest job we'll go get your new panties first", your face goes bright red as she said it loud enough for everyone around you to hear but you know this is nowhere near the worst of whats to come. You can hear some giggles from people around you but most of them probably think your sister was just joking but that doesn't last long as she follows up with "does that sound good to you or do you want to get your panties later?". Her smirk pisses you off but still reply through gritted teeth "lets just go get this over with" but shes not going to let you get away with that as she asks "what was that?, I couldn't hear you i said did you want to buy your panties first or save it for later?" she's started speaking even louder and you realise its only going to keep happening until you give her what she wants. You let out a dejected sigh and say "I want to go buy my new panties first sis", satisfied she gloats "well sure bro, if that's what you want" as she practically skips her way to the first shop whilst you drag your feet and keep your head down hoping to get through this as quick as possible.

You awkwardly follow you sister into the lingerie store and mentally start to prepare your self for whats to come, your sister is already browsing the selecting as you catch up to her "so what type do you prefer, I really like this pair but i'm not sure if they are too similar to the ones your wearing". Your surprised at how seriously she seems to be taking this, almost as if she was just shopping with her sister and not her brother but you know better than to say anything, the best way to get through this is to just go along with it so you take a look at the panties shes holding. She said they were similar to the ones your wearing but to you it doesn't seem that way, they have the same shape but they are a aqua blue with a darker blue lace around the edges. You decided to tell her that they seem fine to you and you don't mind that they seem similar. "Yeah I guess since your getting more it doesn't matter, well that's one pair down and I figure you need at least 8 more to make sure you have enough so lets really get to it". It's only now you notice that there is two store assistants looking at you clearly amused at how serious you are about buying panties clearly meant for yourself, your sister also notices and asks if they could help you to pick out some more pairs and the matching bra's, They eagerly agree deciding that this was just what they needed to kill time while at work.

You were so embarrassed and trying to block out everything that was happening that you didn't want to risk asking why you would need the matching bra's for fear of what your sister might say or do next. It takes a whole 20 minutes but the three girls, with some **** input from you, finally pick the 8 pairs your sister says you need. They consist of a pair of boy shorts, a pair of hipsters, 2 thongs, 2 bikini cut panties and 2 Brazilian briefs in whole range of colours giving you a wide choice what paired with your two standard brief panties. You didn't really know why it was important to have such a variety of types or what they where called but that store assistants where more than happy to give you a thorough lesson on the topic whilst they helped after your sister told them how you wanted to learn all about the panties since you wanted to wear them so much. You wanted to run away as they tried to explain each type in detail as you looked through them all but the glare from your sister made sure you not only stayed but acted like you were interested and grateful for they help, if not you knew she would tell your mom everything. The bra's were equally varied but they didn't explain those as you don't have boobs so they wouldn't really fit anyway, they did however make sure that they would fit someone of your size with C-cup breasts at your sisters instruction. Every so often you noticed your sister taking more pictures for **** material, usually while you where holding a pair of panties and acted like you were really deciding if you liked them or not, or while they measures you for your bra fitting.

Eventually though you leave the shop with your new underwear, your sister made sure she used your card to pay after she got you to tell her your PIN as you let out a sigh for the money that was wasted. "Right so that's one job done, so do we go for clothes next, make up or hair and nail's" you figure your sister is just talking to herself, relieved that now you just have to follow her around as she shops for herself since you've got the panties now. Finally she looks like she settles on what she wants to do next and turns in the direction of your next destination.
